Single and Double Glazed Windows


Graph has been a consistent caterer to individual requirements of its clients, including three glazing options for its glass: single (standard), double, and triple glazing. Graph’s glass range has been a customer favourite, due to:

  1. The elegant look that Graph’s glass offers;
  2. The superior quality and durability of Graph’s glass; and
  3. A plethora of glass colour options to choose from.

Depending on the choice of glazing that you opt for, you could engage in energy efficiency for your house, in consideration with thermal conservation and losses.


A primary consideration for households is the amount of money the customer is willing to spend in order to reduce long-term costs. The more glazing that you opt for, the better the insulation, but comparatively higher the costs. A double-glazed glass might be comparatively more expensive than a single-glazed glass when purchasing a window, but there are a few considerations in place when opting for a glazing choice:

  1. Cost Savings Through Energy Savings
    The airtight construction of glazed windows creates thermal insulation. This decreases the flow of incoming and outgoing heat. The double glazed windows are completely airtight to ensure that the gas (i.e. argon insulation between two glazing windows) does not leak out from the windows. The special construction imparts insulation properties to the windows. The insulation properties of the windows make it difficult for then heat to flow between them. This allows the room to stay at one particular temperature scale for a longer period of time. The room can be heated up faster or cooled down quickly depending on the needs of the occupants. The speed of the operation means that the heater or the cooler will need to run for a lesser period of time. This allows more energy to be saved which in turn decreases the amount of money required to pay the energy bills.
  2. Prevention of condensation and frost
    The air between two panes of glass and the airtight seal can prevent the condensation from building up by blocking moisture in the cold weather. Our double-glazed windows retain heat for longer periods of time which prevents frost from being formed.
  3. Sound Insulation Properties

Sound insulation is often a major concern for those living in buildings located in noisy areas. Graph’s double-glazed windows can form a barrier between the room and the outside environment. It reduces the entry of sound from the outside. Moreover, internal noise can’t reach the outside environment. These windows have an excellent property when it comes to sound insulation.

  1. Safety aspect
    Safety is one of the major concerns while installing glass panes on windows. Double glaze windows are tougher to break as compared to simple glaze window. A single pane of glass can be broken quite easily. Hence, they ensure the security to the homes. Additionally, the seals used for double glazed windows are tighter. This makes it harder for people to force the windows open from the outside. This increases the security of the house as well.
  2. Reduction of Harsh Sunlight
    Sunlight can be extremely harsh in some places. Sunlight contains UV rays which can cause a bleaching effect on many materials. It reduces the risk of damage to the items exposure to the sunlight. Our double glazed glass reduces the amount of sunlight entering the room. The paintings, the carpet, the furniture and other sensitive items in the room will last for a longer period of time if these windows are installed to reduce the sunlight entering the room.
